Subtitling method and system

Hughes, CJ; Armstrong, M

Abstract

A method of retrieving supplementary data related to audio-video content with reference to a reference version of that content involves deriving an audio signature from audio-video content. The audio signature is searched against reference audio signatures of reference versions of the audio-video content. If a match is found, supplementary data related to the reference audio-video content is retrieved. The search is a directed search using data extracted from the transmission route by which the audio-video content is to be delivered to a consumer. The search process is thereby more efficient as the search may be started at an appropriate location or conducted in an appropriate direction, rather than searching blindly.
